What I'm looking for

I seek engineering roles solving data platform and pipeline challenges, with ownership, mentorship opportunities, and measurable business impact.

I am a Senior Data Engineer with over five years designing and optimizing data pipelines and cloud data platforms, focused on improving data quality, reducing costs, and accelerating analytics.

I have built CDC processes, master data management pipelines, and data quality monitoring applications using tools like Airflow, dbt, Snowflake, Soda, and Splink, and I deploy containerized solutions with CI/CD.

My work has delivered measurable business value: cutting pipeline costs by 20% (~$680/month in one engagement), speeding queries by 70%, and automating processes that saved $20,000/month.

I lead and mentor engineering squads, align technical solutions with business goals, and contribute to open-source projects and community initiatives to continuously improve practices and outcomes.
